Daft Punk "integral" to 'Tron Legacy'

Tron Legacy director Joseph Kosinski has said that French electro act Daft Punk are "integral" to his upcoming blockbuster.

The filmmaker told journalists at Comic-Con that Daft Punk, who are working on the score for the Disney sequel, that the duo's work is "blurring the lines between sound design and music".

He said: "I've been working with Daft Punk for almost three years on this film. It's a new direction for them, it's a combination of orchestral, electronic and granulate sound. It blurs the line between sound design and music.

"Because we started so early I was able to play tracks on set to get actors in the mood. I think that the picture and the music are so integral to each other it's really exciting to see."

Tron Legacy opens in 3D, IMAX and conventional cinemas on December 26.
